Technicians dangle from a series of ropes before polishing the underside glass at Grand Canyon Skywalk in Hualapai Reservation, Ariz. The more than 40 panes of glass underneath the horseshoe-shaped bridge on the Hualapai reservation aren’t easily accessible. The structure juts out 70 feet from the edge of the Grand Canyon, offering visitors a view of the Colorado River 4,000 feet below. (AP Photos/Abseilon USA, AZ Photos, George Walsh)
